In the world of Mobile applications, there are plenty of options available when it comes to selecting the right technical stack. There are many different frameworks and languages available for developing mobile applications, out of which React Native and Kotlin are the two most popular choices for mobile application development. Both tools have their advantages, features, and use cases which developers need to consider before making a decision.
Today in this article we will deep drive in both frameworks and will make it easy for readers to make the correct decision. So, let’s get started.
What is React Native?
React native is an Open-Source JavaScript framework that was developed by Facebook in 2015 and it has gained popularity among developers as it also allows the development of cross-platform mobile applications, using React native developers can build cross-platform applications using a single code-base – Write once and deploy it on Android and iOS platforms.
Key features of React Native
- Cross-Platform Support: React native is mainly developed to support cross-platform development for mobile applications. It allows developers to use a single code base for iOS and Android mobile applications. Which helps in reducing the time and cost of the overall project.
- Combination of React and JavaScript: React native uses Java Script, a widely used programming language, and React, the most popular JavaScript library used for UI building. Developers who are familiar with React and Web development can take advantage of existing skills to build mobile apps.
- Native-like performance: Mobile applications created in react native look like native and give a smoother experience because they use native components that bridge the gap between web and native components.
- Hot reloading: One of the most useful and significant features of react native is reloading, it allows developers to check the result of latest code changes without re-running the application. Which results in quick debug and development.
- Large Community: Being a react native developer you can take advantage of large community support. Developed by Facebook, long presence in the mobile development market it has a large developers community that works continuously towards the framework growth.
- Declarative UI(User Interface): React native uses a declarative UI approach, where developers have to describe the required UI and react native will take care of updating and rendering UI.
- Support for native modules: React native has opened the way for developers to use modules developed in native languages like Java, Objective C , Kotlin etc. This helps developers to use platform specific features and good performance experience.
Advantages of React Native
- Mobile applications developed using react native gives native like performance and developers can use a single code base to build Android and iOS developers.
- Due to single code base – Multi platform application build it helps firms to reduce overall cost of project.
- Large and Strong community is a strong reason for developers to choose react native as a mobile development platform. Strong library availability helps developer in rapid development.
What is Kotlin?
Kotlin is a modern programming language developed by JetBrains, It was first introduced in 2011 as an alternative to Java, targeting the Java Virtual Machine (JVM). At first, It was initially launched to be used as a plugin in Android Studio. Later in May 2017 Kotlin was declared as the official Android Development language. It is the third language that fully supports Android development after Java and C++. The goal behind introducing Kotlin was to address various lacking features in existing programming languages, particularly Java while maintaining seamless interoperability with Java. Nowadays Kotlin has become most popular among developers and its community has increased in a large scale.
Key Features of Kotlin
After talking about how the journey of Kotlin was started, now we will look into key features of Kotlin that attract developers towards it.
- Concise code and readability: Kotlin is known for its concise syntax that helps developers to reduce boilerplate code. This makes code very easy to understand and more readable.
- Null Safety: One of the very popular and powerful features of Kotlin is its Null Safety feature, that distinguishes Nullable and non-Nullable types.This feature helps developers to prevent null pointer exceptions which is a very common issue in programming languages.
- Interoperable with Java: Kotlin is fully interoperable with Java, allowing developers to use existing Java libraries and frameworks seamlessly. This interoperability makes it easy to adopt Kotlin in projects with an existing Java code – base.
- Large scale audience adoption: Continue contributions of developers to its plugin and library making its community large and strong. Kotlin’s ecosystem has grown significantly in recent years.
- Coroutines support: To manage asynchronous tasks in a very easy and effective manner Kotlin comes up with the most powerful feature – Coroutines. Coroutine comes up with suspend functions which allow developers to pause and resume background processes.
Advantages of Kotlin
- In the form of extension functions, Kotlin allows developers to add new methods in existing classes without modifications in those classes.
- Apart from Android developers, back-end developers are also moving towards Kotlin due to its features like null safety and conciseness.
- Kotlin came up with Coroutines, which has made asynchronous programming more easy and readable compared to traditional callback based approach.
React Native vs Kotlin
